ICE-BREAKING BOAT.

SPECIFICATION formingpart of Letters Patent No. 374,205, dated December6, 1887;r Application filed June 16, 1887. Serial No2-11,547. (Nomodel.)

To LZZ whom, it may concern:

Be it known that I, WILLIAM It. SoHooLEY, a citizen of the UnitedStates, residing at Trenton, in the county of Mercer and State of NewJersey, have invented certain new and useful Improvements in Ice-Boats;and I do declare the following to be afull, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and tothe letters and figures of reference markedthereon, which form a part of this specification.

My invention relates to iceboats, and has for its object to construct aboat which will expeditiously and thoroughly break up the ice in riversand harbors and other bodies of water to open up navigation, theconstruction ofthe parts being such that they are strong andcomparatively inexpensive, and which can be readily applied to boats orcrafts without specially constructing the craft for the application ofthe breaker thereto.

To the accomplishment of the foregoing ends `the invention consists inthe construction and the combination of parts hereinafter particularlydescribed, and then specifically defined by the claims, reference beinghad to the accompanying drawings, forming a part hereof', and in which.-

Figure l is a plan of the boat, showing en- Fig. 2 is a side elevationof the boat. Fig. 3 is a detail of lifting mechanism. Fig. 4 is aperspective of the breakers.

In the drawings, the letter A designates a boat, which may be of anyordinary and wellknown construction. To a suitable part thereof, say tothe bowportion, there isjournaled in suitable bearings a shaft, B, whichhas on each end, and, say, outside or beyond the sides of the vessel, apulley or wheel, C, andbetween its ends a pulley or wheel, D. To thesame shaft are secured, in manner to turn or swing thereon, the arms orbars E, which carry at their forward or free ends a shaft, F, which isjournaled so as to revolve. This shaft has keyed to it the wheels or4pulleys G, andV between its ends is provided with a series of arms, H,arranged around the shaft in a man- .taper toward both ends,

ner that they will be out of line with each other, as indicated in Fig.4. These arms are each formed of flanged or double T-iron, and and areformed with a hole, @,betwecn the ends, in which hole is formed a seat,b, to receive a key, so that when the arm is slipped over the shaft itmay be secured theretoby a key, c, thus firmly and rigidly securing thearm to the shaft. Each arm is also provided at each end with a pick ortooth, I, which preferably projects from both faces of the arm. By theconstruction of arm described I obtain comparative lightnesscombined'with strength, and at the same time have the picks set at suchaposition and distance apart that they willeiectually break the ice andpermit it to pass off without choking the arms. A belt or chain, J, willconnect the pulleys C and G, so that power may be transmitted from shaftB to shaft F to revolve the latter. The shaft B derives motion from anengine, K, located at any convenient part Vof the vessel, through asuitable connectionsay a chain or band, L-between pulley D and a pulleyor wheel, M, on a double-crank shaft, N, which connects with the enginethrough the pitman-rods O.

`W'hen the breaker is operating, the parts are in the position shown inFig. 1, and when not being operated the shaft carrying the pick-arms israised and supported by suitable means above the bow ofthe boat. Themeans I consider best for the purpose consist of a shaft, P, journaledin suitable supports, Q, on the bow ofthe boat and provided with acog-wheel, R, with which engages a worm, S, on a shaft, T, which mayhave a hand-wheel, U, for operating it. Ropes or chains V passaround'shaft P, and at their other ends connect by suitable means-a sayby hooks d-with theswinging arms E, the ropes or chains passing overpulleys e, journaled in the upper ends of the standards W. By turningthe worm-shaft t-he ropes or chains will be wound upon the shaft P, soas to lift the swinging arms and breakers carried at the end thereof.

The arms or breakers may be supported in their raised position by anysuitable means-- for instance, a ratchet, f, on shaft P--and a pawl, g,engaging therewith will hold the shaft P at any desired point, and thushold the arms 2.
